    加载 bbr

    /sbin/modprobe tcp_bbr
echo "tcp_bbr" > /etc/modules-load.d/modules.conf

    lsmod | grep bbr

    返回值应为

    tcp_bbr     20480  1

    配置 sysctl

    echo "net.core.default_qdisc = cake" > /etc/sysctl.d/99-sysctl.conf
echo "net.ipv4.tcp_congestion_control = bbr" >> /etc/sysctl.d/99-sysctl.conf

sysctl --system

    检查

    sysctl net.ipv4.tcp_available_congestion_control
sysctl net.ipv4.tcp_congestion_control
sysctl net.core.default_qdisc

    返回值应为

    net.ipv4.tcp_available_congestion_control = reno cubic bbr
net.ipv4.tcp_congestion_control = bbr
net.core.default_qdisc = fq_codel
